"We've found many objects including the only canon which survives in the world today from the battle of Trafalgar and Admiral Horatio Nelson's seal used for his correspondence. The explanation for the existence of that seal is interesting because it has an inscription of a decoration he received after he had been on the Agamemnon in 1729 after the Battle of the Saints, which indicates that at some point he gave that seal to the boat or the tripulation as a gift, as a remembrance that the boat was his favorite until the day of his death."

The treasures found in a British battleship shipwrecked off the South American coast, in an area known to nineteenth century travellers as the "navigator's nightmare", are being shown at an impressive exhibition in Uruguay.
The collection of naval artefacts were found on the HMS Agamemnon - a battleship that fought in the Battle of Trafalgar captained by Admiral Lord Nelson.
The sunken warship was recently discovered six hundred metres (yards) away from the Uruguayan coast.
Divers found the shipwreck lodged on the seafloor, after a six-year search by marine archaeologists.
Shipwrecks were not uncommon in this area - it was renamed the "navigator's nightmare".
Many of the ships that sank more than a century ago are still under water.
Miraculously, many objects still remained inside the sunken haul - and in other shipwrecks - all currently on exhibition at the Naval School in Montevideo, Uruguay's capital.
Many artefacts of historical importance are now out of the water, among them: an iron 24 pound canon and a silver pocket seal with an "N" which is believed to have belonged to commander Admiral Horatio Nelson.
Three thousand gold coins were recovered one by one from interior areas of various shipwrecks in Rio de la Plata.
The treasure hunters and divers use specialised metal detectors to discover tiny objects and bigger ones such as the canon of the Agamemnon.
The exhibition has been organized by treasure hunters and Uruguay's' navy.
It shows one-of-the kind priceless objects recuperated from the Agamemnon itself.
The war ship is mostly known for its participation in the Battle of Trafalgar which led to the victory over the Spanish Armada, ensuring British supremacy of the seas for the following century.
For three of the most crucial decades in British naval history, the Agamemnon always seemed to be at the centre of the action, having no less than eleven battle honours.
Its last mission was in 1808 in the South Atlantic, based in Rio de Janeiro.
The Agamemnon was wrecked and sank north of Gorriti Island in Maldonado Bay, Uruguay.
